[blfs-dev] Dependencies in X chapter

Hi,

As you may have seen, I have added xorg-env as a dependency of xbitmaps. But
since xbitmaps is required by Xorg applications, which also requires mesalib,
which requires xcb-proto and the like, it may be not necessary. However,
theoretically, a user following the dependencies for X server backward may end
up building xbitmaps as the first package in the X chapter (I agree that the
probability is small). Furthermore xscreensaver requires only Xorg
applications (well, that is king of weird to me, but Armin has arguments about
the server running remotely). In this case, the probability is slightly higher.

There is also something which bothers me: when a dependency refers to X Window
system, where should the user begin? The id "x-window-system" refers to the
beginning of the chapter, but nowhere it is said what should be built to get a
working X installation (actually, the xcb-util-xxx packages are not needed for
a basic installation, and neither are xclock, twm, xterm nor xinit, although
the last four are useful to do the first tests of Xorg).

BTW, shouldn't twm be added to the deps of xinit, at the same level as xterm
and xclock? Right now xterm and xclock are "required (runtime only)", and twm
is not mentioned. Strictly speaking, none of the three are required, even at
runtime: you could build another terminal (say rxvt), forget about xclock,
build another WM, and start them in ~/.xinitrc. Of course, If you keep the
defaults, xclock, xterm and twm are started by xinit? So I suggest to put them
as "recommended (used by default at runtime)".

Regards
Pierre
